Abstract
Methods and systems for adjusting a scoring measure of a search result based at least in part on the breadth of a previously-executed search query associated with the search result are described. In one described system, a search engine determines a popularity measure for a search result, and then adjusts the popularity measure based at least in part on a query breadth measure of a previously-executed search query associated with the search result. The search engine may use a variety of query breadth measures. For example, the search engine may use the quantity of results returned by the search query, the length of the query, the IR score drop-off, or some other measure of breadth.
Claims40
A method comprising:
- estimating, by a server device implemented as a single computer system or as a network or cluster of computer processors, a breadth of a search query;
- identifying user interaction with a first document in a result set that is responsive to the search query;
- changing, by the server device, a ranking of a popularity of the first document based at least in part on the user interaction with the first document and the breadth of the search query, wherein an amount of the change in the ranking of the popularity decreases with increased breadth of the search query;
- and
- making, by the server device, the ranking of the popularity of the first document available for responding to a subsequent search query.
An article comprising one or more machine-readable data storage media storing instructions operable to cause one or more machines to perform operations comprising:
- estimating a breadth of a search query;
- identifying user interaction with a first document in a result set that is responsive to the search query;
- changing a ranking of a popularity of the first document based at least in part on the user interaction with the first document and the breadth of the search query, wherein an amount of the change in the ranking of the popularity decreases with increased breadth of the search query;
- and
- making the ranking of the popularity of the first document available for responding to a subsequent search query.
A system comprising:
- a server device implemented as a single computer system or as a network or cluster of computer processors, the server device programmed to perform operations, the operations comprising:
- estimating a breadth of a search query;
- identifying user interaction with a first document in a result set that is responsive to the search query;
- changing a ranking of a popularity of the first document based at least in part on the user interaction with the first document and the breadth of the search query, wherein an amount of the change in the ranking of the popularity decreases with increased breadth of the search query;
- and
- making the ranking of the popularity of the first document available for responding to a subsequent search query.
